Specification of Letters Patent. I

Application filed November 27, 1912. Serial N 0. 733,800.

To all whom it may concern: 7

Be it known that I, THOMAS REYNOLDS, a citizen of the United States, and a resident of Brooklyn,'co'unty of Kings, and State of New York, have invented a new and useful Improvement in Machine-Tools, of which such as presses, lathes, milling machines and the like, wherein it isdesirable to convey the product thereof to one destination,

and the dust, shavings, headings, etc., to another destination, and to insure their com plete separation. Obviously, various means and devices may be employed for this purpose, although in my preferred form I employ an intermittent blast of air or the like to blow the dust,-etc., to o'ne receptacle, and a cut-off in connection w1th the product conveying means, which cut-off is opened only I when the blast i's'discontinued.

In the accompanying drawings, 1' have illustrated my invention in connection with press employed for finishing or shavin the sides of matrix blanks and the like, a ter they have been otherwise formed, in order to bring them to the exact size required; but it w ll be apparent that the invention is similarly a plicable to many other kinds of machines, W erein'it is desirable to' secure similar'results. Generally speaking, I desire it to beunderstood'that I do not limit myself to any specific form or embodi- -ment, except in so far as suchlimitations are specified in the claims.

Referring to the drawings: Figure l is a perspective view of a portion of the machine, having my invention applied thereto; Fig. 2 is a transverse vertical section, on an enlarged scale, through. the plunger, etcL; Fig. 3 is a sect1on,,taken substantially on the 4 is a perspective view of the blank, which is the product of the machine and designed for a linotype matrix; Fig.5 is a partial perspective view of the machine; Fig. 6 is a detail, partly broken away, of thevalve controlling means; and Fig. 7 is a sectional detail, illusblank.

Referring to the drawings, the blanks X areas usual stacked ina magazine A, and

engaged by the stud when the slide recedes.v

the operation of the plunger .on the are fed oneby one therefrom underits' foot the plate E by the reciprocating ineath it, and the blank is forced through a 'sultable opening in the plate E ('see Fig. 7

and its edges arebrought to the exact size next blank thatis brought into operative position by the slide B. l

The features and operations so far deand constitute no part of my present invention.

scribed are old in the art As the finished blanksX are moved in the manner described, they ordinarily pass downward one by one through .a tube F and Patented Mar. 7,1916.

required, this being'effected by the removal in front of an advancingand compacting de- I vice, such as the star wheel G, whereby they are assembled in, the trough or way H. In

the past, considerable inconvenience has been experienced by, the delivery with T the blanks X of the shavings or headings X and it is one of the purposes of my invention to correct this difficulty. To that end, I provide the tube F witha cutofi', preferably in the form of a pivoted flap O, which is periodically opened in-any desired manner. In

theform shown, it is mounted on the-rock shaft 0 which carries also an armO con-" nected to the operating link P. 'The link P is formed .with an elongated slot P, which is R connected to the re ciprocating slide B,- slot P is of sufiicient length to permit considerable lost motion in relation to the stud R. .Through theconnections described, the flap 0 will be'opened each time the slide B advances, and will fall to its closed position To render the closing action more certain, a spring 0 is emit being noted that the ployed, which spring is connected to the frame work-and to the arm 0 ings X are blown by an intermittent blast of air, or the like, from a. pipe K into the The shavfunnel J, and thence through a tube J into the receptacle J The blast is automatically controlled, so that it acts only when the cutoff or flap O isclosed, and in this way the shavings or headings are prevented from following the blanks X'into the tube F.

The blast apparatus comprises the piping K, from which it is directed onto the work inproximity to the plate E and member D, and also the piping L, through which the air is delivered from any suitable source of supply. The blast is controlled and ren-J dered intermittent by the valve M (see Fig. 6) located at the extremity of the piping L and normally held against the seat L The valve M is connected. to the stem M which passes through the stationary sleeve M and is connected at its outer end to the abutment M between which and the sleeve M is located the spring M tending to hold the valve normally in its closed or inoperative position.

dinally movable actuating rod N, one end 0f which contacts with the abutment M position even when the pressure is relieved in the piping L. Due to the construction and arrangement already described, and due to the relative timing of the slide B which opens the cut-off O, and the rod N which controls the valve M, the cut-off will be closed when the blast is in operation, and consequently the shavings or headings X will be exeluded. from the tube F; and the cut-off will be opened when the blast is discontinued, and the blanks X will be advanced,

- so that they will be delivered one by one into the tube F and the other devices previously mentioned.

As previously stated, I have herein shown my invention in preferred form and by way of example, and as applied to a specific type of machine, but obviously many variations and alterations therein, and in its mode of application, will suggest themselves to those skilled in the art and still be comprised within the scope of the appended claims.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows: 1. In a machine of the class described,

Suitablymounted in the framework is the longituthe combination of a receptacle for the finished product, a cut-ofi therefor, a'blast apparatus to convey the waste material in the direction of the receptacle, means for rendering said apparatus active and inactive alternately, and means for. closing and openingthe cut-off as the blast apparatus is rendered active and inactive, respectively; whereby the receptacle for the finished product will be closed whenever the blast apparatus is in operation.

2. In a machine of the class described,

the combination of means for conveying the product thereof to one destination, and a blast apparatus to convey the waste material in the same direction and comprising a controlling Valve to convey the waste material to another destination, the said product conveying means and valve being ope'rated at different times.

3. In a machine of the class described, the combination of means for conveying the product thereof in one direction, and a blast apparatus to convey the'waste material in the same direction, the said product-conveying means comprising a conductor, and a cut-off to close the conductor,

together with means for closing and opening the cut-off as the blast apparatus is connected and disconnected respectively; whereby the conductor will be closed whenever the blast apparatus is in operation.

4.1 1 a machine of the class f described,

the combination of means for conveying the finished product in one direction, and a blast apparatusadaptedto deliver intermittent blasts of air to convey the waste material in the same direction, the said product conveying means comprising a con-' ductor, a transfer device to carry the product thereto and operated between the intermittent blasts of air, and a cut-off to close the conductor and connected to the transfer device so as to be opened by its advancing movement and -closed by its retreating movement; whereby the conductor will .be closed when the blast apparatus is in operation. I

5. In a machine of the class described, the combination of means for conveying the product thereof to its proper destination, the said means comprising a cut-off; a blast apparatus to convey the waste material to another destination, the said apparatus comprising a controlling valve; and means connected to the operating machine elements whereby the cut-off is closed when the controlling valve is opened, and vice versa.

6. In a machine of the class described, the combination of blank trimming means, a device to discharge the blanks from the machine, a conductor to receive the discharged blanks, a cut-off for the conductor adapted to be closed and opened periodically, a blast apparatus to eject the waste" material in the direction of the conductor, and mechanism to insure the closing of the cut-off while the blast apparatus is in op:

' eration.

7. In a'machine-of the class'described, the combination of a receptacle for the finished product, a cut-off therefor, periodically-operated means to convey. the waste material in the direction of the'receptacle, and means for opening and closingthe cutreceptacle will be closed whenever the con- .veymg' means are in operation.

In testimony whereof I hereunto set my hand this 23rd day of November, 1912, in

the presence of .two, attesting witnesses.
